摘要：
The emission properties of Si1-xGex alloy nanocrystals (nc-Si1-xGex) in an optical microcavity were studied, and the results were compared with those of nc-Si in the same structure. The cavity consists of two distributed Si/SiO2 Bragg reflectors (DBRs) sandwiching a thin SiO2 film containing nc-Si1-xGex. The commonly observed cavity effects, that is, spectral narrowing, high directionality, and photoluminescence (PL) enhancement in the normal direction, were observed. In nc-Si1-xGex, PL lifetime was lengthened by cavity formation, while that of nc-Si was shortened. This difference is due to the different dielectric contrast between active layers and DBRs.
